November 6, 2009, Newsletter Issue #51: Lumicon Filters For Astrophotography
Tip of the Week
There are a number of different Lumicon filters you can use for astrophotography, depending on the object you intend to photograph. The Lumicon Deep Sky Filter is the best product among the line for nearly every application of astrophotography, including photographing stars, nebulae, and galaxies. The Deep Sky Filter works by blocking out certain types of light, such as airglow, and improving the photographic images of deep sky objects.
For very faint nebulae, you should the Lumicon Night-Sky Hydrogen-Alpha Filter, or Deep Sky Filter. The Night-Sky Hydrogen Alpha Filter works well with reflectors and has an intermediate level of performance with Schmidt-Cassegrains. However, it does not work as well with refractors. Other Lumicon filters such as the Minus Violet Filter will work well with astrophotography as well.
